Specification of Letters Patent.

Application filed April 3,1905. Serial No. 253,398.

To all whom it may concern..-

Be it known that I, ALEXANDER GREGG, a citizen of the United States, residing at Detroit, in the county of Wayne, State of Michigan, have invented certain new and useful Improvements in Window-Screens and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying draw ings, and to the figures of reference marked thereon, which form a part of this specification.

This invention relates to window-screens; and it consists in the construction and arrangement of parts hereinafter fully set forth, and pointed out particularly in the claims.

The object of the invention is to provide a window-screen wherein the arrangement is such as to enable the screen to be readily placed in position in a window and quickly and easily removed. A further arrangement provides for the vertical adjustment of the screen within certain limits and for swinging the screen to a horizontal position.

The above object is attained by the construction illustrated in the accompanying drawings, in which Figure 1 is a fragmentary view in perspective, showing a window-screen involving my invention in position in a window. Fig. 2 is a fragmentary view in elevation, showing the position of arts when the screen is swung to a horizonta position and showing by dotted lines the manner in which the screen may be removed. Fig. 3 is a central vertical section through the window with a screen therein and the inner sash raised. Fig. 4 is a rag mentary view in detail of a modified form of the attaching means which secure the screen in the window.

Referring to the characters of reference, 1 designates the window-casing, and 2 the sill. Secured to the outer faces of the blind-stops 3 are the keepers 4, the central portions of which are raised, forming between the inner walls of said keepers and the faces of said stops the ways 5, in which are adapted to lie the projecting ends of the pins 6, which are formed integral with the lates 7, attached to the opposite stiles of the screen-frame 8, which is fitted between the blind-stops and is covered with a suitable wire-netting 9. The height of the screen is such as to cause its upper sash 10 to lie contiguous to the lower rail of the upper sash.

The keepers 4 permit the pins 6 to slide vertically therein'and afford a limited vertical movement of the screen without displacing it, which movement is permitted because of the fact that the keepers are out of the path of the screen-frame. The length of the slots 5 formed between the inner faces of the keepers and the outerfaces of the blind-stops allows the pins 6 to be withdrawn therefrom when the screen is swung to a horizontal position, as shown by dotted lines in Fig. 3, and tilted, as shown by dotted lines in Fig. 2,

vertical movement of the thereby enabling the pins to be simultaneously withdrawn from the keepers and the screen to be readily removed from the window when desired. The arrangement described enables the screen to be easily replaced in the window by simply reversing said operation.

By swinging the screen to a horizontal position upon the pins 6 an opening is afforded through the window for the passage of an article therethrough without removing the screen. To return the screen to its proper position when its lower end is swung downwardly, beveled lugs 12 are secured to the sill 2, which direct the lower rail 13 of the screen into place. To afford stops which will prevent the bottom of the screen from swinging outwardly, there are employed upon the outer faces of the blind-stops, near their lower ends, the plates 14,which project beyond the edges of said stops and engage the edges of the screen-frame, as clearly shown in Fig. 1. The same results may be attained by forming a vertical slot 15 in the inner edge of each of the blind-stops instead of mounting the keepers 4 upon said stops and mounting the pins 6 in the edges of the screen-frame to engage in said walls, as shown in Fig. 4; but the arrangement shown in the other views of the drawings is preferred, as it obviates the labor incident to the cutting of the grooves 15.

Having thus fully set forth my invention, what I claim as new, and desire to secure by Letters Patent, is

1. The combination with a window-frame, of the keepers mounted thereon out of the path of the vertical movement of the screenframe and having vertical ways therein, a screen adapted to fit within the windowframe, pins projecting from the screen-frame and lying Within the slots of said keepers, the length of said slots being such as to permit of the vertical movement of the screen-frame and the removal of said pins from said keepers by tilting the screen-frame sideWise.

2. The combination With a Window-frame, of the keepers secured to the outer sides thereof, said keepers having vertical Ways therein, a screen adapted to fit Within the window-frame, plates secured to the outer faces of the opposite sides of the screenframe between the top and the bottom thereof, pins projecting from said plates adapted to lie in the vertical slots of the keepers, the

length of said slots being such as to allow the I 5 simultaneous insertion of the pins therein, and a simultaneous removal of the pins therefrom by tilting the screen --frame sidewise, beveled lugs on the sill to direct the screen into place and stops to prevent the bottom of the screen from swinging outwardly.

In testimony whereof I sign this specification in the presence of two Witnesses.

ALEXANDER GREGG.
